Výskyt velkých šelem ve vybraných oblastech moravských a slovenských Západních Karpat

Greguš, Štefan January 2016 (has links)
The research The occurance of large carnivores in areas of Moravian and Slovak Western Carpathians focused on field study of carnivores European brown bear Ursus arctos, gray wolf Canis lupus and Eurasian lynx Lynx lynx in Velká and Malá Fatra (Slovakia). The study was held from August 2014 till February 2016. During 23 field control were identified 12 presence traits or evidences from all three species. Apparently, there are 10 individuals of wolf, 73 bears and probably 13 individuals of lynx in Velká Fatra. Between 5 and 8 wolfs, 8 individuals of lynx and probably 65 bears in Malá Fatra.

Hodnocení vlivu struktury krajiny na disperzi rysa ostrovida v Pošumaví / Assessment of the impact of landscape structure on the dispersion of lynx in Posumavi

Sladová, Michaela January 2014 (has links)
Assessment of the impact of landscape structure on the dispersion of lynx in Posumavi Abstract: The big predators are a traditional group of bioindicative species, whose presence shows the state of environment and landscape within a region. As these animals recolonize the cultural landscape of central Europe it's needed to understand their space requirements and habitat preferences. The lynx (Lynx lynx) has been one of the Sumava forest species since the 70's. After almost 40 years the population of lynx has spread from Sumava and Bavarian Forest to forested parts of Cesky Les, Smrcina and Novohradske hory and to both sides of state borders. However today's state of lynx population, stable number of animals or genetic variability is endangered by many factors. Long term viability of the lynx population is - besides poaching or illegal hunting − affected by the loss of suitable habitats and ongoing fragmentation of the landscape. One of the possible solutions of negative impacts is delineation and protection of landscape permeability of habitat corridors. They might have provide supply of new individuals to small, extinction prone population and at the same time they could reinforce overall fitness population. This thesis has three main objectives:1) evaluation of landscape fragmentation and connectivity in...

Ochranářská genetika rysa ostrovida v Západních Karpatech / Conservation genetics of Eurasian lynx in the Western Carpathians

Ungrová, Lenka January 2021 (has links)
Robust monitoring combined with genetic analyses are important approaches to protect and manage large carnivore populations successfully. The aim of this master thesis is to analyse Eurasian lynx (Lynx lynx) population within whole Slovakia for the first time using 15 microsatellite loci. Noninvasive genetics is an effective tool for monitoring animal species with large home ranges and low population densities. Noninvasive samples including feces, hair, urine and buccal swabs were collected together with tissue samples from dead (mostly roadkill) individuals. 187 samples were collected between 2017-2019, resulting in 59 successful genotypes. Two samples were incorrectly determined in the field and excluded from further analyses since they were wildcat samples. For population genetics analyses and demography, the dataset from the "Veľké šelmy 2" project was extended with 98 genotypes in collaboration with the Institute of Vertebrate Biology CAS. Overall, 68 lynx individuals were detected in the dataset of 155 genotypes. Relatedness analysis resulted in 67 significant relationships of the first degree and 9 significant relationships of the second degree. These results suggest a high relatedness among the whole population. According to the present thesis, Slovakian lynx population has the third lowest...

Projekt podpory veřejného mínění o rysovi ostrovidovi (Lynx lynx) u dětí a mládeže v regionu Prachaticko / Project support of public opinion about European lynx (Lynx lynx) in children and youth in the region Prachaticko.

ŠVERÁKOVÁ, Barbora January 2011 (has links)
Eurasian Lynx (Lynx lynx) is included in the IUCN. It was extirpated in the Czech Republic at the beginning of the 19th century and is found thanks to the reintroduction since 1980 in the Czech Republic again. It is only wild feline in the Czech Republic. Lynx population has lost its growing trend and is decreasing mainly due to poaching. The project ?Support of public opinion about European lynx (Lynx lynx) in children and youth in the region Prachaticko? was created as a precaution against poaching. The project involved over 275 children and students. They gained new information through the teaching program in school subjects Biology, Art and Gymnastics and they made your own opinion about Lynx. Lynx is only carnivorous animal, which was and still is part of the Bohemian Forest.

Funkční konektivita a kvalita biocenter nadregionálního významu v přeshraničním prostoru NP Šumava a Bavorský les / Functional connectivity and quality of biocentres in the border area of Šumava and Bavarian Forest National Parks

EFFENBERKOVÁ, Lenka January 2012 (has links)
The Bohemian Forest, a mountain range located in Central Europe on the border between the Czech Republic, Germany and Austria, has many well-known qualities. The areas of Modravské slatě moors and Trojmezná, are considered to be the most valuable biocenters in the Czech part of the Bohemian Forest. This Master thesis confirms the quality of these areas in a transboundary context Natura 2000 habitats and their representativeness. A new transboundary (European) biocentre is proposed and its importance for several species is discussed.

Analýza životaschopnosti ohrožených druhů zvířat v České republice / Population viability analysis of endangered species in Czech Republic

Šťastná, Andrea January 2017 (has links)
Diploma thesis analyzes the viability of the selected species populations in the Czech Republic. The thesis is divided into two main parts. The first part contains a stochastic model simulating possible scenarios of the Eurasian lynx population size in the Czech Republic. For this model program Vortex was used. The second part is focused on Time series analysis of the Grey Partridge and the Common Kingfisher population, where data was obtained from the Czech Society for Ornithology. This analysis aims on identification of factors that may affect the viability of the two bird species.
